Ambry Genetics

Jun 27, 2022

The c.220C>T (p.R74W) alteration is located in exon 3 (coding exon 3) of the EBF4 gene. This alteration results from a C to T substitution at nucleotide position 220, causing the arginine (R) at amino acid position 74 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
